The High Court advised that a defendant’s admission that a substance was cannabis, considered alongside other evidence, could provide sufficient prima facie proof for a cannabis possession charge to proceed without a laboratory certificate.
Mr Justice Charleton delivered the judgment on 8 May 2007 in a consultative case stated from Cork District Court. The District Court judge had asked whether the defendant’s admission alone was enough to identify the substance as cannabis in the absence of a certificate of analysis.
The case stated recorded that the defendant had been stopped and searched in Hollyhill, Cork. Gardaí found a small quantity of brown substance in his back trouser pocket. After caution, he said it was cannabis and for his own use. A pipe described as a “hash pipe”, a knife and a balaclava were also found during a further search. The substance was sent to the Forensic Science Laboratory but, according to the judgment, apparently never returned.
At the close of the prosecution case, the defence submitted that there was no case to answer because no analysis certificate had been produced. The High Court explained that at this stage a judge asks whether the evidence, taken at its highest, could allow a properly directed tribunal of fact to convict. The judge should not weigh evidence or decide credibility, though a case must be stopped if the evidence is absent or so tenuous that a conviction would be unsafe.
Mr Justice Charleton advised that the admission was admissible evidence against the defendant and should be considered in its factual context, including the pipe and knife. He said an admission that a substance is cannabis may be relied on as evidence of its identity, though the person making it does not necessarily know what they are talking about. Expert evidence is therefore not always required at the direction stage.
The court’s advice was that, in the circumstances recorded, there was sufficient prima facie proof to allow the charge to proceed. It did not decide whether the defendant was guilty. The judgment stressed that the trial court must ultimately assess the evidence against the criminal standard of proof beyond reasonable doubt, including whether the defendant could safely be relied on to identify the substance.
